The victim, who is only identified as a 25-year-old teacher in the police report, was walking in the park about 8:30 p.m. when four juveniles started punching him. One of the attackers yelled "Worldstar," a reference to the popular web site "Worldstarhiphop.com" where fight videos uploaded daily.

According to the police report, the man fought back and tore the shirt off of one of the juveniles, and the group then ran south on foot toward Eastern Avenue. The victim suffered only a scratch on his nose and refused medical treatment, the report says.

"I fought them for at least five solid minutes, then you just walked away," the person wrote. "Thanks a lot."

It was not immediately clear whether the person on Reddit was the same victim. The post had generated more than 100 comments in response.

The suspects were described in the police report as black males, each between 13 and 15 years old. The suspect who was recording wore a red shirt and was about 5-foot-5 and weighed 190 pounds, while the others stood about 5-6 or 5-7 and weighed less than 190 pounds.

Earlier this week, Mayor Stephanie Rawlings-Blake and Police Commissioner Anthony W. Batts walked through downtown and the Inner Harbor, in part to discuss efforts to reach out to young people who they say have been causing trouble in the tourism district. Also this week, the City Council passed one of the strictest curfew laws in the nation.

Had the curfew been in effect Thursday, the suspects would not have been in violation — it requires youth under 14 would need to be home by 9 p.m. year-round, and teens 14 to 16 years old wold have to be home by 10 p.m. on weeknights.

A 31-year-old man who was sentenced to 20 years in prison in Baltimore after he pleaded guilty to possessing 5.9 grams of marijuana won an appeal Wednesday invalidating the plea — raising the possibility that he will be released.
